Analysis on Application Results of Different Coring Methods in the Hole WFSD-1 of Wenchuan Earthquake Fault Scientific Drilling Project
Abstract:Multi-type and multi-size split barrel coring technology were used in the hole WFSD-1 of Wenchuan earthquake fault scientific drilling project to ensure high core recovery rate and keep the cores in original state even in very complicated formation conditions. As a result, 94.3% of core recovery was achieved and the cores were in good original state, which meet the requirement of geo-scientific research.
